✦ Synopsis

1.5418), with scan width 1.6O (20) plus al-a2 divergence, 28max=130°. Out of 5277 measured reflections 4945 were considered observed with IFo@~u((FoI). Lorentz, polarization and absorption corrections were applied. The structure was solved by direct methods and refined by full matrix least squares using SHELX7614 with all non-H atoms refined anisotropically. The H-atoms were located from difference Fourier maps. Final R&=0.0497/0.0726 for observed data using a weighting scheme w=l/(02(Fo)t0.00007F02).
